What type of dog is right for me?

I have 2 cats, a medium sized house, with a medium size lawn and a pool and there is a big park and a forest not 5 minutes away. i am looking for a medium sized dog that is easy to train. i was thinking about a Brittney but they are hard to get, and i was considering a siberian husky but i heard it didnt like cats. i would like a dog that likes water. Oh and i want the dog to be by my side and sleep/snuggle with me... PLEASE HELP!!!
